Figure 11. HRTEM images of as-prepared TiO₂ with (A) 90% and (B) 80% (101) facet, and (C) 75% (001) facet, and (D-F) their corresponding ³¹P MAS NMR spectra of TMP-adsorbed TiO₂. Theoretical models and calculated adsorption energy (E_ad) between TMP and Ti_5C sites on various TiO₂ facets, including (G) (001) facet, (H) (101) facet, and (I) the reconstructed (1 × 4) (001) facet (Ti: light grey; O: red; P: orange; C: grey; H: white).
